Order and Disorder in the Feldspars, I

Crystallographic Laboratory, Cavendish Laboratory, Cambridge, England

Summary: Feldspar structures are classified into small-cell (c ≈ 7 Å.) and largecell (c ≈ 14 Å.) types, as a preliminary to a discussion of the nature of substitution disorder, position disorder, and stacking disorder, and of the relations between them. Diffraction effects characteristic of the different types of disorder are considered and related to experimental observation as far as possible.
